A comment on the beta hazard rate distribution
IEEE Transactions on Reliability, 2016We point out that the beta hazard rate distribution introduced by Lai and Jones is a particular case of Libby and Novick's beta distribution known since 1982.

Inference for a hazard rate change point
Biometrika, 1991Summary: We discuss inference based on the likelihood ratio process for a hazard rate change point. A random change of time scale transforms the empirical process into a Poisson process which enables us to derive large deviation approximations to the significance level of the likelihood ratio test.

For right-censored lifetime data with possible left-truncation, (1.6) of Example 1.3 defines penalized likelihood hazard estimation. Of interest are the selection of smoothing parameters, the computation of the estimates, and the asymptotic behavior of the estimates.

A General Model for the Hazard Rate with Covariables
Biometrics, 1979with the coeffiicients of the various powers of time being possibly diffierent functions of the vector of covariables. Methods for fitting the model to data and testing hypotheses about model parameters are presented. The degree of the polynomial for the hazard is chosen in a step-wise manner as part of thefitting of the model.

The first chapter of this book recalled for the reader that Gnedenko, Belyaev and Solovyev [1] approved the bathtub curve after generic considerations. Now we can go back to this endorsement which constitutes a weak point of Gbedenko’s seminal work.

The analysis of unemployment duration in this study is based on the concept of the hazard rate and of the survivor function which were introduced in chapter II.2 about search theory. In the present chapter the design of explanatory hazard rate models for individual unemployment duration is considered in detail and empirical findings are surveyed.

How to Identify a Bathtub Hazard Rate
IEEE Transactions on Reliability, 1987The Total Time on Test (TTT) concept is a useful tool in several reliability contexts. This note presents a new test statistic, based on the TTT plot, for testing if a random sample is generated from a life distribution with constant versus bathtub-shaped hazard rate.
